Hello I'm building a watch well bread boarding it. I normally use a Ds3231 RTC chip. Well right now there is none unless i buy a few of them from amazon. And if i just buy one it cost more that way. So iwas wondering if anyone know of any Real time clock modules that keep great time like the Ds3231 That can work with the arduino? I have a bunch of 1307 well really bad at keeping time.
Hello hammy. Yes the 3231 yes the best i have used The problem isthe footprint is tp large for my Project I'm working on the Board is way small. I think the Crystal on the 1307 I have is not that good. I'm going to try to get a better crystal from mouset and see if that works.
The accurcy would be great. But when loses minutes a month is a problem. And the project I'm working on no room for a GPS module. I'm working on a time clock project that has a very small pcb board. More like a watch design in away.
Yes I have and I have one. It doesn’t have a real time clock on it. Mine is a desk clock small but not to big. The little prototype board I have doesn’t have much space left. I’m thinking of making a second one soon.
